晶霰 的英文怎麼說
中文拼音 [jīngxiàn]
晶霰
英文
labile shower-
The main mechanism of enhancing precipitation is that much ice nuclei turn into ices, and then snow ; graupel are formed more by microphysical processes. the melting of graupel makes precipitation more than that of unseeded clouds
主要的增雨機制是大量冰核活化成冰晶，冰晶通過增長和其他的微物理過程形成雪晶、霰，霰最後融化成降水使地面降水量增加。The influence of the cloud droplet spectrum character and the spectrum growth and change is considered, which does not use a cut - off value for conversion from cloud water into rain water process. in the continuous coalescence equation, the particles fall velocity difference is not moved out from the integral, but is integrated in the equation as the function of diameter d to avoid the error of using particles average fall velocity. in the new scheme, generation rate of graupel due to the collection of snow by graupel and the collection of cloud ice by graupel are included
雲中凝結核ccn的數濃度採用超幾何函數表示；雲水向雨水的自動轉換過程採用grabowski （ 1999 ）的公式，考慮了雲滴譜的特徵和發展變化對該過程的影響，而不是採用原方案給定閾值的方法描述該過程；對連續碰並方程不再將粒子落速差作為常量提出積分號外，而是直接作為粒子直徑函數在積分號內求解，這樣處理可以迴避使用粒子群的平均落速帶來的誤差；增加了霰和雪、霰和冰晶的碰並微物理過程。A complex mixed - phase explicit microphysical parameterization scheme, which also be known as reisner 2 explicit scheme was developed for use in the ncar / penn state mesoscale model versions ( mm5 ). the single - moment schemes has additional variables for graupel and ice number concentration, in which the mixing ratio of cloud water, rain water, cloud ice, snow and graupel are predicted and number concentration specified
Mm5中的reisner2方案是一種含霰的復雜混合相顯式雲物理方案，該方案包含了雲水、雨水、冰晶、雪和霰的混合比預報方程，同時對冰晶的數濃度作了預報。Using the 1ap 3 - d hailstorm numerical model, we analyze influence of variation on rainfall amount, hail fallout amount, dynamical process of cloud, microphysical process, mechanism of hail suppression with seeding, and seeding outcome. besides, we use those study outcomes and bring forward some advice about using and improving model. we simulate a hailstorm occurred in nanjing county and analyze influence of raindrop, ice crystal, graupel size distribution on outcome of model
本文利用中國科學院大氣物理研究所的三維冰雹雲催化數值模式，通過對冰雹雲的模擬和對譜參數的數值試驗結果，分析了冰雹雲中粒子譜形的變化，對雲和降水過程的影響，其中包括雨滴譜、冰晶譜、霰譜的形狀參數對自然雲的發展過程、降雨降雹、雲中微物理過程、霰以及冰雹的形成機制的影響。The results show that it has no effect on cloud development and cloud structure, when form factors of raindrop, ice crystal, graupel size distribution ( r, i, g ) vary respectively, r variation has a bigger effect on rainfall amount and hail fallout amount, a, variation has a smaller effect on rainfall amount and hail fallout amount
並利用這些研究結果，對雲模式的使用和改進提出建議。對1988年5月3日發生在南京的冰雹雲個例分別進行了雨滴譜影響的數值試驗、冰晶譜影響的數值試驗、霰譜影響的數值試驗以及雨滴、冰晶、霰譜影響的數值試驗。The results indicated that vaterite crystals have been induced by vesicle system
結果表明囊泡體系誘導了球霰石晶體的產生。Finally, a fouling crystal treated with electromagnetism is compared with that of untreated under an electric microscope. they were found to have different structure. the fouling crystal treated with is less compacted in structure
4 、將經過電磁處理的污垢晶體和未經過電磁處理的污垢晶體在掃描電鏡下進行觀察和分析，發現電磁抗垢技術的機理是改變了污垢晶體的結構，由緻密型的霰石變為鬆散型的方解石。分享友人
